There are many toxic and harmful substances, and many organic pollutants in the fine chemical wastewater are toxic and harmful to microorganisms, such as halogen compounds, compounds, dispersants or surfactants with bactericidal effect; There are many biodegradable substances, B is lower than C, and the biodegradability is poor; The wastewater generated during the production of water-based chemical products is characterized by large discharge, high toxicity, high concentration of organic matter, high salt content, high chroma, high content of refractory compounds, and great difficulty in treatment, but at the same time, the wastewater also contains many available resources, and membrane technology, as a high-tech production and processing in the chemical field Energy conservation, consumption reduction and cleaner production play an important role. Technical background of catalytic micro electrolysis treatment technology recommended for physicochemical process of industrial wastewater pretreatment Organic wastewater treatment, especially the treatment of high salinity and high concentration organic wastewater, has always been a problem of concern to many domestic environmental protection workers and management departments. With the rapid development of China's chemical industry, various new types of chemical products have been applied to all walks of life, especially in heavy polluting industries such as medicine, chemical industry, electroplating, printing and dyeing. While improving product quality and quality, they also bring about increasingly serious environmental pollution problems. The main forms are: high concentration of organic pollutants in wastewater, stable structure, and poor biochemical properties, Conventional processes are difficult to achieve standard emissions, and the treatment cost is high, which brings pressure on enterprises to save energy and reduce emissions.
